To begin the dewatering process, you need to pump the slurry into the frame type sludge filter press so that solids are spread evenly. The filtrate leaves the filter plates via the corner outlets into the manifold, producing clean liquid. Solids accumulate on the filter cloth, making a filter cake. The cycle is finished when the chambers are filled with the filter cake, which can be discharged. For high capacity frame type sludge filter press, fast action automatic plate shifters are used to help in speeding up the process. If you are going to use a frame type sludge filter press in hostile settings such as chemical manufacturing plants, there are filters specifically meant for such places. They are designed to operate in 24 hours for a smooth production process.

Filter presses come in different sizes, and each size is suitable for use in specific areas. Some of the places where a frame type sludge filter press can be used include mining, power generation, steel mill, municipal sewage treatment plants, food and beverage processing, and cement production. If you need a machine that suits your industry's needs, you can have it customized. During customization, some of the factors considered include cake dryness requirements, filtration cycle time, manual or automatic plate shifters, and cloth life. The overall design of the frame type sludge filter press can also be modified to suit your style. Another important thing to note is that these machines are mostly made from steel because they are strong and durable.

Filter presses were first used in the Ceramic Industry over one hundred and sixty five years ago. Since that time they have been used in numerous applications so much so that it is referred to as the “work horse” of the filtration world.
Typical applications being:-
And there are many more industries where filter presses are used….
In recent years, several factors, including the Statutory Legislation controlling discharge to waste of unsuitable effluents, shortage of land for lagoons or drying beds, shortage of water and in some industries a search for additional by-products of a process, have brought about a new appraisal of filter presses.
Where the material to be filtered contains finely divided solids especially in the sub-sieve and sub-micron sizes, and where it is difficult to separate the liquid from the solid, a greater force is required to effect the separation efficiently. The filter press can produce a higher pressure than either the centrifuge or the rotary vacuum filter or belt filter. It is often the only unit suitable for filtering slurries, which have low filtration rates.
